目的 采用多层螺旋CT（MSCT）测量腰椎椎间孔数据，探讨其临床应用价值。方法 分析2021年2月至2022年12月期间我院的50例腰椎间盘突出症患者临床资料；入组患者均行螺旋CT检查。比较腰3/4-腰5/骶1左右两侧椎间孔宽度、高度、长度；神经根下缘至椎间孔下缘距离，椎弓根内侧、外侧至正中矢状面距离，上关节突、下关节突至正中矢状面距离，椎弓峡部至正中矢状面距离。结果 腰3/4-腰5/骶1各节段椎间孔高度、宽度、长度左右对比无统计学差异（P>0.05），腰3/4-腰5/骶1各节段椎间孔高度、宽度呈降低趋势，差异具有统计学意义（P<0.05）。腰3/4-腰5/骶1各节段椎弓根内外侧、上下关节突、椎弓峡部至正中矢状面距离左右对比无统计学差异（P>0.05）。腰3/4-腰5/骶1各节段椎弓根内外侧、上下关节突、椎弓峡部至正中矢状面距离逐渐增大，差异具有统计学意义（P<0.05）。腰3/4-腰5/骶1各节段神经根下缘至椎间孔下缘距离左右对比无统计学差异（P>0.05），腰3/4-腰5/骶1各节段神经根下缘至椎间孔下缘距离逐渐增大，差异具有统计学意义（P<0.05）。结论 腰3/4-腰5/骶1椎间孔面积逐渐减小，但神经根下缘至椎间孔下缘距离逐渐增大，行侧入路椎间孔镜操作时，通道操作的范围也随之增大。
